Patent DE-3474062-D1 (DE)
Title: Encapsulated device for measuring length or angle
Inventor: MILLER WALTER DR
IPC: B23Q11/08
Filed: 1984-09-28
Granted: 1988-10-20
Abstract: An encapsulated length or angle measuring system includes a follower or a coupling member which extends through a slit in a housing of the measuring system. Thus slit is sealed off against harmful environmental influences by sealing elements which extend along the slit and are spread open by the coupling member in the region where the coupling member passes out of the housing through the slit. This spreading of the sealing elements can result in sealing problems. In order to provide better sealing, the sealing elements are formed as thin, resilient metal sheets which define chambers on their active sealing surfaces which contain a sealing fluid. This sealing fluid, by means of adhesion and capillary action on the follower or coupling member, seals off the extremely fine gaps which are typically present between the follower or coupling member and the sealing lips.

Title: Process for making shredded potato products
Inventor: WANG MARTHA YIN
IPC: A23L19/12
Filed: 1984-03-29
Granted: 1988-11-10
Abstract: Ready-to-eat shredded potato products having a pleasant texture, and a substantially uniform off-white to golden tan color, are obtained by the process of the present invention. A potato dough is formed under low temperature and low shear mixing conditions so as to avoid overgelatinization of the potato starch and tackiness which would impede flowability and the continuous production of long continuous shred layers. Individual discrete dough pieces having a moisture content of from about 29% to about 50% by weight are tempered to distribute the water substantially uniformly throughout the dough pieces, the tempered dough pieces are shredded and the shredded dough is cooked. Producing substantially homogeneous discrete dough pieces without first producing a dough mass is achieved by spraying a premix of the dry ingredients with water as the ingredients are tumbled to form agglomerates. Tempering is necessary to obtain continuous flowability of the dough pieces into and through feed hoppers and the shredding rolls over extended periods of time. The shredded 'potato products can be cooked by frying or by baking. The dough is formed from at least one potato starch source which is pregeiatinized or precooked and in comminuted or particulate form. Cooking of the I pregelatinized or precooked at least one potato starch source in the presence of water is not performed until after the shredded product is formed. This avoids overgelatinization and tackiness which would impair flowability to and through the shredding mills. Shredded potato products made from at least one potato starch source and cereal grains can be made by admixing a pregelatinized or ungelatinized cereal grain with at least one potato starch source.

Granted: 2000-11-16
Abstract: High quality silicon oxide is grown for integrated circuits by oxidizing poly-crystalline silicon under an oxygen gas flow. A diffusion stop layer of thermal silicon nitride is formed on the underlying substrate priorto the deposition of the poly layer to be oxidized. The nitride layer isolates the substrate from diffused oxygen within the poly layer during oxidation, permitting a non-critical, extended oxidation time. Extension of the oxidation period eliminates imperfect or "loose" chemical bonds throughout the oxide layer formed. Corner stress common in trench applications is minimized because the nitride prevents oxidation in the substrate. The oxidation of undoped poly over doped poly proceeds conformally because the nitride layer therebetween inhibits the enhanced oxidation effect of impurities in the doped poly.

Subsequently, the throughput and the line speed are increased simultaneously, such that the weight/ metre is maintained substantially constant until any one of a plurality of parameters such as line speed, screw speed, motor load current, extrudate temperature, melt pressure, etc reaches a predetermined maximum value. Thereafter either the line speed or extruder throughput is adjusted such as to maintain the weight/metre of the extrudate substantially constant at the desired value.
